I want to determine if a lat/long point is inside the perimeter of the City of Calgary. This are the coordinates: 51.0644894,-114.081923. Google tells me they are within the city limits so it must be true.

Thanks @iant. This did it. I was getting an error: ERROR: transform: couldn't project point (51.0645 -114.082 0): latitude or longitude exceeded limits (-14) but was able to fix it by switching the long/lat coordinates around.
